摘　　要：同构识别是机构类型综合中一个重要而又困难的问题，同时，也是图论中非常难解决的问题之一。以往探讨的同构识别方法均为纯低副平面运动链，对含高副平面运动链的同构识别，目前还没有一种方法．本文首次提出一种对含高副平面运动链进行同构识别的方法，该方法速度快、工作量少，经大量实例计算，该方法是一种行之有效的好方法，且运动链杆件数越多，其优势越明显．Isomorphism identification is an important and difficult problem in mechanism type synthesis, it is also one of the most difficult problems in graph theory. All former methods of isomorphism identification just studied planar kinematicchains containing only lower pairs. Up to now, no method of isomorphism identification on planar kinematic chains containing higher Pain was found. In this paper an method concerning this problem is offered for the first time the method has the advantage of high sped, less working processes. It is proved to be and efficient method after lots of practical calculation, and its advantage hereines more apparent with the increase of the number of links of chains.
